DESCRIPTION
The Fujitsu MB811L323229 is a Single Data Rate Interface Fast Cycle Random Access Memory (FCRAM*)
containing 33,554,432 memory cells accessible in a 32-bit format. The MB811L323229 features a fully synchro-
nous operation referenced to a positive edge clock whereby all operations are synchronized at a clock input which
enables high performance and simple user interface coexistence.
The MB811L323229 is utilized using Fujitsu advanced FCRAM core technology and designed for low power
consumption and low voltage operation than regular synchronous DRAM (SDRAM).
The MB811L323229 is dedicated for SiP (System in a package), and ideally suited for various embedded/
consumer applications including digital AVs and image processing where a large band width and low power
consumption memory is needed.
